Bldg Codes & Safety Codes Pertaining to Seismic Zone

Indian Standards on Earthquake Engineering :-

National Standard Body of India, is a Statutory Organization under theBureau of Indian Standards Act 1986.

Formulation of Indian Standards on different subjects of Engineering throughvarious Division Councils.

The Civil Engineering Division Council :- standardization in the field of CivilEngineering including

A) Structural Engineering,

B) Building materials and components,

C) Planning Design

D) Construction and Maintenance of Civil Engineering Structures

E) Construction Practices

F) Safety in Building etc.

These standards are evolved based on consensus principle through anetwork of technical committee comprising representatives from Govt. &Non Govt Organizations.

IS 1893:1984 Criteria for Earthquake

Resistant Design of Structures

Deals with earthquake resistant design of

structures and is applicable to buildings;

elevated structures; bridges; dams etc.

Also gives a map which divides the country

into five seismic zones based on the seismic

intensity.


3

IS 1893(Part 1):2002 Criteria for Earthquake Resistant

Design of Structures : Part 1 General provisions and

Buildings’ :-

Contains provisions that are general in nature and applicable to all

structures.

Also contains provisions that are specific to buildings only.

Covers general principles and design criteria, combinations, design

spectrum, main attributes of buildings, dynamic analysis, apart from

seismic zoning map and seismic coefficients of important towns, map

showing epicenters, map showing tectonic features and lithological map

of India.


4

IS 1893(Part 4):2005 `Criteria for Earthquake Resistant Design of Structures: Part 4 Industrial Structures Including Stack Like Structures

This standard deals with earthquake resistant design of the industrial structures (plant and auxiliary structures) including stack-like structures such as process industries, power plants, textile industries, off-shore structures and marine/port/harbour structures.


5

IS 4326:1993 Earthquake Resistant Design and Construction of Buildings - Code of Practice

Provides guidance in selection of materials, special features ofdesign and construction for earthquake resistant buildings includingmasonry construction, timber construction, prefabricatedconstruction etc.

In this standard, it is intended to cover the specified features ofdesign and construction for earthquake resistance of buildings ofconventional types.

The general principles to be observed in the construction of suchearthquake resistant buildings as specified in this standard areLightness, Continuity of Construction, avoiding/reinforcingProjecting and suspended parts, Building configuration, strength invarious directions, stable foundations, Ductility of structure,Connection to non-structural parts and fire safety of structures.


6

IS 13827:1993 Improving Earthquake Resistance of Earthen Buildings –Guidelines

The guidelines covered in this standarddeal with the design and constructionaspects for improving earthquakeresistance of earthen houses, without theuse of stabilizers such as lime, cement,asphalt, etc.


7

IS 13828:1993 Improving Earthquak

e Resistance of Low Strength

Masonry Buildings – Guidelines

Covers the special features of design and

construction for improving earthquake

resistance of buildings of low-strength

masonry.


8

IS 13920:1993 Ductile Detailing of Reinforced Concrete Structures Subjected to Seismic Forces –Code of Practice

Covers the requirements for designing and detailing ofmonolithic reinforced concrete buildings so as to give themadequate toughness and ductility to resist severe earthquakeshocks without collapse.

Material specifications are indicated for lateral force resistingelements of frames.

The provisions are also given for detailing of reinforcementin the wall web, boundary elements, coupling beams, aroundopenings, at construction joints, and for the development,splicing and anchorage of reinforcement.


9

IS 13935:2009 Seismic Evaluation, Repair and Strengthening of Masonry Buildings – Guidelines

Covers the selection of materials andtechniques to be used for repair and seismicstrengthening of damaged buildings duringearthquakes.

Also covers the damageability assessmentand retrofitting for upgrading of seismicresistance of existing masonry buildingscovered under IS 4326 and IS 13828.

SP 7 : 2016

National Building Code of India 2016 (NBC 2016)

First published -1970 at the instance of Planning Commission

First revised -1983.

Three major amendments were issued to the 1983 version, two in 1987 andthe third in 1997. S

Second revision - 2005, to which two amendments were issued in 2015.

The National Building Code of India (NBC), a comprehensive building Code, isa national instrument providing guidelines for regulating the buildingconstruction activities across the country.

Serves as a Model Code for adoption by all agencies involved in buildingconstruction works be they Govt or Non Govt agencies.

Mainly contains administrative regulations, development control rules andgeneral building requirements; fire safety requirements; stipulations regardingmaterials, structural design and construction (including safety); building andplumbing services; approach to sustainability; and asset and facilitymanagement.

Building Bye Laws :

Earlier there are different Dev. Control Regulations in differentUrban areas of state

In year 2017 Govt. introduced CGDCR-2017 to avail ease &uniformity in interpretation & appropriated enforcement ofDevelopment Control Regulations.

Government has prepared a comprehensive document for smoothimplementation & interpretation of Regulations under GujaratTown Planning & Urban Development Act - 1976

It is called as Comprehensive General Development ControlRegulations – 2017, which is finalized wide Govt. NotificationDt.03/10/2019

All urban Development Authorities, Area Development Authorities& Municipal Corporations classified in D1 to D10 categories

Which is divided in three parts

Part I :- Procedure Regulations

Part II :- Planning Regulations

Part III :-Performance Regulations
